So did you finish the testing and get the 3x3 <1mR beam at full power you were trying to get?
I think that's what people are waiting to hear about, preferably with pictures to drool over

Aww... can we not have photos now to bide the time and lessen the pain of waiting??
- There is no such word as "can't" -
- 60% of the time it works every time -
Not yet, I don't want to get bombarded with requests suddenly until I have these last set of optics and know all the price data.
I am busy like crazy and struggling with time already so certainly don't want bombarding with questions. Will have a solution that works and very well.
Just a thought, who would be interested in 1.5mrad and who 0.8mrad, I guess when I have confirmed the expected results I should give two beam options as the costs will be similar but the optics combination are very different.

Me too, or even 3x1mm @ 1mrad, so you could stack up 3 to a 3x3mm'ish beam
Andy: could you reveal just a little about what kind of optical setup you are using ? - is it a cylindrical lens setup like the one Drlava is offering in another group buy, or what ? would be interesting if you could just collimate each diode, then knife-edge/pbs-combine, and then run the whole shebang through the correction optics, to get a round'ish beam out..
Thanks !

EDIT: Thanks for the PM I got with the link to the GB should have looked down further.!!
strike:/ My apologies, I read through this thread but continued to get lost as to who is doing the group buy or if there is one. It seemed to change ownership. Could someone enlighten me to the current proposed price and time frame if any at this point also who is organizing it.
Thanks
John

Hi Guys, please spread the word that the group buy is on the other thread.

Seams people on this thread don't know about it.
I am also not getting messages relating to this thread anymore, seams there is a bug in PL.

The fast axis of the diode is the smallest close to the diode looking like this: | . But the fast axis is also the high divergent one, so after 30 meters it looks like this ----
With a prism pair you can met the small beam (|) wider like this [] so the divergence gets smaller so you end up with a beam after 30 meters like this - instedd of this ----
With knive edging you just stack the 2 beams as close as possible next to each other like this || after 30 meter it will look almost the same as with only one diode like this ----
With one prism pair you should be able get it down to this -
get it?
Please note, this works with Blue diodes, I have not tested this with the red diodes as we are all waiting for the reds.
